Moonlight Gourami Care Guide: The Glowing Centerpiece Fish
The Moonlight Gourami (Trichopodus microlepis) is one of the most elegant gouramis in the hobby. Its silvery, almost luminescent body seems to glow under aquarium lighting — hence the name — and males develop striking orange-red fins as they mature. Peaceful, graceful, and a true centerpiece fish, it’s a wonderful choice for a calm community tank. Here at Tropical Treasures in Cheyenne, gouramis are some of our most-loved labyrinth fish.
A quick heads-up: we don’t currently stock the Moonlight Gourami itself, but we carry several close relatives — most notably the Pearl Gourami, the Moonlight’s nearest cousin in the Trichopodus genus. Ask us and we’re happy to special-order or point you to a comparable fish. Here’s everything you need to know to keep one thriving.
Moonlight Gourami at a glance
Moonlight Gouramis are a medium-large gourami from Southeast Asia, reaching about 5–6 inches. They’re peaceful and a little shy, with the same air-breathing labyrinth organ that lets all gouramis gulp air from the surface. If you love the look but want something in stock now, browse our community fish collection — the Cosby Opaline is another large, hardy centerpiece gourami worth a look.
Tank size & setup
Because of their adult size and active swimming, Moonlight Gouramis need at least a 30-gallon tank, with larger being better for a group or community. Provide a calm setup with plenty of live plants and some floating plants for cover and security — they use fine plant material to build bubble nests when breeding. Gentle filtration is ideal, since they dislike strong current, and a snug lid keeps the warm, humid air above the water that labyrinth fish need.
Water parameters
Moonlight Gouramis are hardy and adaptable, thriving in temperatures of 78–84°F, pH 6.0–7.5, and soft to moderately hard water. A reliable heater keeps them in their warm comfort zone, and you should always dechlorinate new water with a quality water conditioner before water changes. Stability matters more than chasing an exact number.
Diet & feeding
Moonlight Gouramis are omnivores with hearty appetites. A varied diet of quality flakes or pellets, supplemented with frozen foods like bloodworms, brine shrimp, and daphnia, keeps them colorful and healthy. They’ll also nibble at some soft plant matter. Feed small portions once or twice a day and avoid overfeeding.
Temperament & tankmates
Moonlight Gouramis are among the more peaceful gouramis, making them excellent community fish. Pair them with other calm, similarly sized species — think peaceful tetras, rasboras, corydoras, and other gentle gouramis. Avoid fin-nippers and overly boisterous tankmates that will stress them. For more on choosing centerpiece gouramis, see our Honey vs Dwarf Gourami guide. The Honey Gourami and even the playful Kissing Gourami show the range of the family.
Breeding
Moonlight Gouramis are bubble-nest builders. Unlike many gouramis, they often incorporate plant fragments into their nests. A well-fed pair in a quiet, warm, well-planted tank with a lowered water level will often spawn readily. The male tends the nest; once the fry are free-swimming, feed infusoria and other tiny foods until they’re large enough for baby brine shrimp.
